See https://en.wikipedia.org/wiki/Joe_Flacco?veaction=edit - for example, references 24 and 25 under the section "2012 season: Super Bowl MVP". It looks like one of them is using Template:R, which may explain the problem, but I'm not sure if the icon not rendering properly is a template problem or a VE problem.
From that article, references 25 and 26 (from {{r}} and <ref> respectively) generate: {{r}} -> <span about="#mwt97" class="reference" data-mw="…" rel="dc:references" typeof="mw:Transclusion mw:Extension/ref" data-parsoid="…">[25]</a></span> <ref> -> <span about="#mwt99" class="reference" data-mw="…" id="…" rel="dc:references" typeof="mw:Extension/ref" data-parsoid="…"><a href="…">[26]</a></span> Is this just because the CSS isn't being applied when it's "mw:Transclusion mw:Extension/ref" as opposed to just "mw:Extension/ref"?
Also in https://en.wikipedia.org/wiki/Michelle_%28song%29 sourced to the sfn template, it looks like.
